Echinacea plant named ‘Green Jewel’

ABSTRACT

A new and distinct cultivar of  Echinacea  plant named ‘Green Jewel’, characterized by its compact and upright plant habit; moderately vigorous growth habit; freely flowering habit; large single inflorescences with light green-colored ray florets; and strong peduncles that hold the inflorescences above the foliar plane.

Botanical designation: Echinacea purpurea.

Cultivar denomination: ‘Green Jewel’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea purpurea, and hereinafter referred to by the name ‘Green Jewel’.

The new Echinacea originated from an open-pollination of an unnamed selection of Echinacea purpurea, not patented, as the female, or seed, parent with an unknown selection of Echinacea purpurea, as the male, or pollen, parent. The new Echinacea was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled environment in Hummelo, The Netherlands in 2004.

Asexual reproduction of the new Echinacea by divisions in a controlled environment in Hummelo, The Netherlands since 2005, has shown that the unique features of this new Echinacea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Green Jewel has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Green Jewel’. These characteristics in combination distinguish ‘Green Jewel’ as a new and distinct cultivar of Echinacea:

-   -   1. Compact and upright plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely flowering habit.     -   4. Large single inflorescences with light green-colored ray         florets.     -   5. Strong peduncles that hold the inflorescences above the         foliar plane.

Compared to plants of the female parent selection, plants of the new Echinacea are more compact and are more freely flowering.

Plants of the new Echinacea can be compared to plants of the Echinacea cultivar Jade, disclosed in U.S. Plant Pat. No. 13,769. In side-by-side comparisons conducted in Lisserbroek, The Netherlands, plants of the new Echinacea differed from plants of the cultivar Jade primarily in ray floret coloration as plants of the cultivar Jade had white-colored ray florets.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Lisserbroek, The Netherlands during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Echinacea production. During the production of the plants, day temperatures ranged from 18° C. to 35° C. and night temperatures ranged from 10° C. to 20° C. Measurements and numerical values represent averages for typical flowering plants. Plants were about two years old when the photographs and description were taken.
